Hipulse - Single Phase ‘1+N’ UPS System

130 kVA - 110V

CHAPTER 5

Operating Instructions

5.1Introduction

The UPS can be considered to be in one of three operating conditions:

Normal operation

All relevant power switches and circuit breakers closed, the load is powered by the UPS.

Shutdown

All power switches and circuit breakers open - no load power.

On Static Bypass

The load power is supplied through the mains static bypass line. This may be considered as an intermediate operating condition being utilized for the purpose of load transfers between inverter and maintenance bypass or supply under abnormal operating conditions.

ECOMODE

All the relevant power supply switches and the battery switch are off, and the load is fed by the Bypass Mains through the UPS Static Transfer Switch, while the Inverter remains on stand-by.

This chapter contains instructions which enable you to switch between the three above conditions, to carry out a RESET after a fault transfer and how to switch OFF the inverter.

5.1.1General notes

Note1: All the user controls and indicators mentioned in these procedures are identified in chapter 1. Some of diagrams are repeated here to assist in understanding the procedures.

Note2: The audible alarm may annunciate at various points in these procedures. It can be cancelled at any time by pressing the ‘Alarm Reset’ push-button.

Note3: The Hipulse UPS System incorporates an optional automatic boost charge facility which can be used in systems containing conventional flooded lead-acid batteries. If this type of battery is used in your installation you may notice that the battery charger voltage may be greater than its nominal (432V d.c. for 380V a.c., 446V d.c. for 400V a.c. and 459V d.c. for 415V a.c. system) when the mains supply returns from a prolonged outage. This is the normal response of the boost charge facility; the charger voltage should return to normal after a few hours.

5.1.2Power Switches

The UPS can be separated by means of power switches, mounted inside the cabinet and accessible after opening the front door, which has a key.

The location of the UPS power switches is shown in Figure 5-1. The UPS module power switches are:

oQ1 - Input MCCB: connects the UPS with he mains supply.

oQ2 - Bypass Isolator: connects the UPS with the bypass supply.

oQ3 - Maintenance Bypass Isolator (Padlocked) permits supply of the load directly by the bypass line for maintenance of the UPS module.

The internal maintenance bypass must not be used when the UPS system is comprised of more

than two UPS modules in parallel.

oQ4 - Output Isolator: connects the output of the UPS to the load.

Note: The battery interrupter is not expected inside of the UPS and should be installed in the proximity of the respective battery bank.
